Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a device uses a single processor to support multiple interfaces, then adaptability is improved, but device complexity increases
Solution Approach 1:
The transmitter is designed with multi-functionality to support multiple transmission modes (single-phase, differential, three-phase) through a single device. The selector circuit chooses between different signal generation paths, and the driver circuit can operate in different configurations, allowing one processor to interface with various devices from different vendors without requiring separate processors for each interface type.
2Adaptability or versatility
If multiple processors are used to support different interfaces, then interface compatibility is improved, but the number of components increases
Solution Approach 1:
The patent merges multiple interface support capabilities into a single processor and transmitter unit. Instead of using separate processors for different interfaces, the invention combines single-phase, differential, and three-phase transmission capabilities within one integrated transmitter, reducing the total number of processors needed in the system.
3Adaptability or versatility
If different interface types are supported, then system design flexibility is improved, but circuit layout area increases
Solution Approach 1:
The transmitter employs universal circuits that can perform multiple functions. The selector circuit routes signals through different paths based on the required interface type, and the driver circuit can be configured for different output modes. This multi-functional design allows various interfaces to be supported within a compact footprint, minimizing the circuit layout area while maintaining system design flexibility.
